Handful of genetic changes led to huge changes to human brain

Changes to just three genetic letters among billions led to evolution and development of the mammalian motor sensory network, and laid the groundwork for the defining characteristics of the human brain, Yale University researchers ...

A single DNA tweak leads to blond hair

A single-letter change in the genetic code is enough to generate blond hair in humans, in dramatic contrast to our dark-haired ancestors. A new analysis by Howard Hughes Medical Institute (HHMI) scientists has pinpointed ...

New method created for identifying genes behind brain tumors

Researchers at Uppsala University have developed a method for identifying functional mutations and their effect on genes relevant to the development of glioblastoma—a malignant brain tumor with a very poor prognosis. The ...

Discovery reveals chromosomes organize into 'yarns'

Chromosomes, the molecular basis of genetic heredity, remain enigmatic 130 years after their discovery in 1882 by Walther Flemming. New research published online in Nature by the team of Edith Heard, PhD, from the Curie Institute ...
